Abstract
Abstract A touch sensitive control panel utilizing pyroelectric material to provide output signals representative of an area touched by an operator includes a plurality of conductors and pads of pyroelectric material selectively in contact with the conductors to provide a binary coded combination of voltage pulses on the conductors representative of a touched area of the control panel.

Claim 1
Independent Claim
163 words
A control panel for an appliance having a multiplicity of operating capabilities, functions and conditions, said control panel comprising: a backing member; a layer of conductive material on a surface of said backing member; a plurality of pads of pyroelectric material at selected locations on said conductive layer; a layer of insulative material on said conductive layer, said insulative layer leaving said pyroelectric pads exposed; a plurality of non-intersecting elongated conductors on said insulative layer; and a graphics display member overlying said conductors, said graphics display member having indicia thereon representative of said operating capabilities, functions and conditions of said appliance; said pads of pyroelectric material being placed on said conductive layer in registration with said indicia and selectively in contact with said conductors so that a binary coded combination of voltage pulses is applied to said conductors in response to a body portion of an operator touching one of said indicia, each of said indicia corresponding to a unique respective binary code.
